An article is a word that goes in front of a noun. There are only three articles: a, an, and the. Their job is to modify a noun. So if you have the noun ‘table’ in a sentence, you can find its article by asking “which table?”. And the answer might be ‘a table’. So ‘a’ is the article.
There can also be another modifier that often goes between the article and the noun, called an adjective. Adjectives describe and give more details about nouns. To find them you should ask a similar question: ” what table?” and the answer might be ‘a brown table’. So ‘brown’ is the adjective.
There is one more kind of adjective called a proper adjective. For example, a person’s name might be ‘Bob’, which is a proper noun. Well, what if you are talking about Bob’s book? Then when you ask the question “which book?” the answer would be Bob’s book. So Bob’s is a proper adjective describing his book. But wait! Here’s something you may have not thought about. You know how proper nouns can consist of more than one word? Like John Jacob Jenkleheimer Smith? Well, what if you’re talking about John Jacob Jenkleheimer Smith’s book? In this case, all four of those words become a proper adjective. Cool.
That’s how you find articles and adjectives.
